Question: A long, flat conducting ribbon of width w is parallel to a long, straight wire; its near edge is a distance a from the wire

A long, flat conducting ribbon of width w is parallel to a long, straight wire; its near edge is a distance a from the wire (Fig. 26.51). Wire and ribbon carry the same current I; it?s distributed uniformly over the ribbon. Use integration to show that the force per unit length between the two has magnitude ? FIGURE 26.51 Problem 81
